ABSTRACT:
An armature coil assembly for magnet-type rotary electric machines such as alternators or motors, which comprises flat conductor pieces or segments with large-area sides thereof arranged parallel to the direction of the magnetic fluxes of a permanent magnet, and a ferromagnetic member inserted between the conductor pieces. The ferromagnetic member inserted provides a magnetic anisotropy in the armature coil along the axis of coil rotation, thus the flow of magnetic fluxes from the magnet through the armature coil to the machine core is facilitated thereby to reduce leakage magnetic fluxes. A stator coil assembly is also made up by using like coil conductor segments.
